I had the same problem:

but only if I run this inside a docker container.

what did you do to solve it?

Sorry, my bad as well, I was passing empty credentials:

amazon.createClient({
  awsId: credentials.AWS_ID,
  awsSecret: credentials.AWS_SECRET,
  awsTag: credentials.AWS_TAG
});

AWS_ID, AWS_SECRET and AWS_TAG were empty string. Maybe it could be a good Idea passing a more specific error

👍

I had the same error caused by passing empty credentials. Thank you @jurgob for specifying what the mistake was! ❤️
